Nice!
Unrelated to your post, but it reminded me....
I was reading something last night about Monarchs. The ones that travel to NE have the furthest to travel, and so need a great deal of pollen (fuel) before their return south. Often, people will plant milkweed to attract them for laying/hatching - which is great - but they don't plant late-flowering plants to provide them the fuel for travel.
So, I guess, it's important for monarchs to not only have milkweed but also late flowering plants.
